# Repository operating rules
NODEDC MISSION CORE is a vendor-neutral mission-control monorepo. Its first
real device plugin investigates an owner-controlled XGRIDS/LixelKity K1 as a
black-box sensor. Preserve the device, the host, the working LAN, raw evidence,
and the boundary between Mission Core and vendor-specific integration code.
## Non-negotiable safety boundaries
- Default to non-mutating discovery or read-only operations. CoreBluetooth BLE
scanning on macOS is active discovery, not passive radio sniffing.
- Do not send BLE writes until the exact service, characteristic, framing,
payload semantics, rollback, and expected state transition are documented.
- BLE notification subscription may perform the standard temporary CCCD write;
disclose it explicitly and do not conflate it with provisioning writes.
- Do not fuzz, brute-force, upload firmware, delete device files, guess SSH/ADB
credentials, or probe unrelated LAN devices.
- Network probes must target the confirmed K1 IP. A full home-subnet scan is
not a default operation.
- Never place a Wi-Fi password in CLI arguments, logs, manifests, source, test
fixtures, or Git history.
- Do not install Python packages globally. Use the repository-local `.venv`
managed by `uv`.
- Do not install or alter Homebrew/system components unless the user explicitly
authorizes that concrete change.
## Evidence rules
- Reference inputs under `docs/reference/` are immutable; write corrections in
audits or ADRs.
- Every real experiment gets a session ID, UTC and monotonic timestamps, a
redacted manifest, operator notes, and SHA-256 hashes for raw artifacts.
- Real PCAP, K1 projects, logs, images, point clouds, credentials, serials, and
router client lists stay out of normal Git. Git LFS solves size, not secrecy.
- Synthetic or explicitly redacted fixtures may be committed under
`tests/fixtures/`.
## Implementation order
Follow the gates in `docs/01_IMPLEMENTATION_PLAN.md`. Do not build heavy
decoders before BLE/Wi-Fi/data-session evidence exists.
## Product UI governance
- For every Control Station, LAB, viewer, or product-presentation change, use
`.codex/skills/mission-core-product-ui/SKILL.md` and follow
`docs/17_PRODUCT_UI_AND_LAB_PRESENTATION_CANON.md` and
`docs/18_APPLICATION_COMPONENT_ARCHITECTURE.md`.
- The integrated Control Station and API have one canonical local endpoint:
`http://127.0.0.1:8000`. Never start a second Mission Core backend on another
port to bypass a stale process. TCP `8765` is legacy Foxglove regression
only, not an operator path. Restart the canonical `8000` process and finish
with no Mission Core backend listening on `8765`.
- `NODEDC_DESIGN_GUIDELINE` is the only visual-design source of truth. Before
editing UI, read its `registry/registry.json`, `registry/components.json`,
`registry/icons.json`, and the relevant component documentation.
- Reuse `@nodedc/ui-react`, `@nodedc/ui-core`, tokens, icons, and page patterns.
Do not create an application-local visual control, interaction state,
geometry, color language, or copy of a design-system component.
- If the required visual entity is absent from the Design Guideline, stop and
obtain explicit product-owner approval. After approval, add it to the Design
Guideline first with registry, documentation, states, and validation; only
then consume it here.
- Domain renderers may remain Mission Core code when they visualize Mission
Core data. Their controls and containing surfaces must still be composed from
canonical Design Guideline exports.
- Product UI must not expose implementation steps, roadmap gates, internal
reason taxonomies, debug controls, placeholder status blocks, or temporary
experiment scaffolding. Keep these in Ops, engineering reports, or developer
tooling.
- Extend one reusable application pattern instead of adding per-LAB layouts.
A new LAB supplies data and renderer configuration; it does not invent a new
page hierarchy or visual language.
- Do not generalize the LAB hierarchy into a universal application template.
For a new non-LAB interface, follow
`docs/19_PRODUCT_SURFACE_EXTENSION_PROTOCOL.md`: identify the operator job,
compare placement/composition alternatives, classify the novelty, and obtain
product-owner agreement before adding a workspace, changing primary
navigation, or introducing a new product root.
- Preserve one product grammar while allowing task-specific composition. A
scene, map, timeline, queue, editor, topology, dashboard, and LAB review may
have different layouts when their entity, lifecycle, or action model differs.
- Preserve the internal dependency direction:
`core → components/renderers → workspaces → composition/App`. Core never
imports workspaces or visual adapters; reusable components never import
workspaces. New domains and LAB runs get their own feature module instead of
growing `App.tsx`, `Workspaces.tsx`, or generic CSS buckets.
- Treat `productModel.ts`, executable versioned contracts, and the experimental
vocabulary as the current local semantic sources. Do not add a parallel
runtime ontology unless the admission conditions in
`docs/18_APPLICATION_COMPONENT_ARCHITECTURE.md` are met.
## Laboratory presentation and reporting
- Use one fixed laboratory presentation contract: selectors, one compact
canonical summary, admitted evidence viewer(s), result, and optional reusable
technical details.
- Keep `missioncore.laboratory-report/v1` executable: bounded `ENNResult.tsx`
modules supply all four `LaboratorySummary` brief fields and use
`LaboratoryResultSummary` for metrics plus proved/not-proved/decision. They
never own canonical summary/result markup. Anatomy changes require a new
version and product-owner agreement.
- The compact summary must explain the decision question, immutable source,
tested method/models/algorithms, experimental mode, principal result,
limitations, and retained authority. It is not the engineering report.
- The complete engineering report belongs in the Mission Core Ops card as
titled structured blocks: objective and architecture stage, source evidence,
method/models/algorithms, worker/runtime, implementation, validation,
results, regressions and limitations, decision, next stage, and acceptance
checker.
- Spatial evidence uses 3D by default. Image-space reprojection may be offered
as a 2D diagnostic mode inside the same reusable viewer. Primary evidence
viewers must provide the canonical expand/restore action.
